They were so small... All of them used to be so small... I wish I could have just loved them normally. Farewell... stay safe. If the world will permit it, I sincerely hope you all find a light at the end of the tunnel.— Isabella about the Grace Field Escapees in "Escape"
Isabella worked as a caretaker in Grace Field House, taking care of the orphans that resides within. Although initially appearing as a loving and affectionate mother towards the children, she actually has a twisted nature and shows much detachment to their tragic fates.
Despite letting 15 children escape from the farm, Peter Ratri and the higher-ups decided to ship out Sarah and promote Isabella to the Grandmother of Grace Field instead. Isabella, however, planned to betray Peter from the very start, confident that her children would come back and that she could help them once that day arrived.
Isabella was born in 2014 and was sent to Grace Field House a year later in 2015. Growing up as an orphan herself in one of the "orphanages", she met a child named Leslie who became her closest friend. She learned a song from him that instantly became her favorite song. Leslie was later shipped out and killed, and the grief caused by the absence of her closest friend made Isabella attempt to escape from Grace Field by crossing the huge wall. When she saw that there was a huge cliff on the other side, however, the sight crushed all her hopes and she was soon stopped by the Mama of her own orphanage.
When Isabella turned twelve and was to be shipped-out, she was given two choices: to be killed by the demons, or train to become a Mama. Isabella chose the latter, since she wanted to live longer than anybody else in order to honor Leslie's memory and become a Mama so she could give all the children as much love as she could.
When Isabella was around 19 years old and still in training, she became pregnant through artificial insemination and she would always sing the same song for her unborn child that Leslie, years earlier, played for her. Sometime later, the newborn was taken away from her and she was appointed as the new mama of Plantation 3, becoming the youngest ever chosen to become a Mama. After a few years being the mama of Grace Field House, she heard Ray singing the same song that Leslie once played for her. She then came to the shocking truth that Ray is in fact her biological son, a revelation that left Isabella in utter horror. Since Ray had figured out the truth behind the orphanage and the outside world, he proposed the idea of becoming her spy, which Isabella accepted.
Isabella was a fair-skinned, tall woman with a pair of deep purple eyes. Her dark brown hair was tied into a bun that hung down onto the back of her head. She wore an attire which consists of a black dress with a white blouse underneath it and a white apron over it. She had the number "73584" tattooed on the right side of her neck.
During her childhood, Isabella wore the orphanage uniform, with a long braid that streams down her back. she has 2 locks of hair in the front of her face as a child, and has large, purple, eyes.
After becoming the Grandmother of the Premium Farms, Isabella was always seen wearing a black dress (presumably the attire for her role as a Grandmother) with long sleeves and a high collar that covers a large portion of her neck.
During her childhood, Isabella was shown to be an optimistic, out-spoken, free-spirited, and fun-loving little girl, who was very attached to her friend Leslie. She had a comedic nature during her childhood, which was displayed when she scared Leslie by popping out of the tree. But ever since she lost Leslie and realized the true motive behind the orphanage's purpose of raising them; to raise them as livestock for the demons, Isabella's personality went through a drastic change. From there on, everything she did; including becoming a Mama, giving birth to Ray, and sending off the orphans to become demon food, was the sake of prolonging her own survival to spite the demons from eating her.
The present Isabella is a sharp-witted, ruthless, cold, manipulative, and deceiving woman. But in her Mama persona, Isabella is capable in putting on a motherly, selfless, and kind-hearted facade whenever she is around the orphans in Grace Field House, and hence was able to earn the trust and love from her foster children. Isabella's behavior is very mercurial, capable of switching between seemingly true affection for the orphans to extreme loathing and threat of violence towards those who defy her. Isabella was unhesitant in taking down those who stand in her way and root out the children that knew of Conny's death, both emotionally, verbally, and even physically.
Another few of Isabella's prominent traits are her high cunning, dominance, and intelligence. As being one of the top Mamas, Isabella uses her intelligence in foiling and sabotaging the orphans' escape plan. She is always shown to be three steps ahead of the orphans' plan and was shown to be quite resourceful, as she depended on her transmitter to track down the orphans. Isabella was unafraid of using her intelligence and position as a Mama to threaten her enemies, as she openly threatens Emma despite knowing it as a reckless and risky move when she seeks to gather information on how Emma and the others are going to escape.
However, beneath everything, she genuinely does love her children, albeit in an extremely twisted way. Due to her own experiences with being an orphan in one of the farms, she reached the conclusion that escape was impossible. So rather than fight what she deemed to be impossible, she instead opted to ensure that the children would at least be able to live happy lives until they were eventually shipped out. The extreme lengths she would go to in order "protect" them and prevent them from escaping is demonstrated when she nonchalantly and violently breaks Emma’s leg, and would then comfort her in her motherly facade as if nothing had just happened. But when the children manage to escape, Isabella gracefully admits her loss and genuinely wishes Emma, Ray, and the other escapees nothing but the best, even covering for their escape while devoting herself to caring for Phil and the other children in the meantime. This shows that becoming a Mama was not solely a means of survival to her - she did genuinely love the time that she spent taking care of the orphans as their mother.
During her reappearance, it is revealed that Isabella has been prioritizing freedom more than anything else ever since she became the Grandmother of the Premium Farms. Her desire to not let anyone rule over her anymore and to escape the wicked farm system became even more amplified ever since she met Peter Ratri. She is willing to put any method to use in order to defeat Peter and the farm system. This includes breaking Nat's fingers and declaring that her children would be disposed of and served as food, all while smiling with depravity; though her acts of cruelty and depravity towards her returned children had been to maintain Ratri's confidence until the opportune moment, at which point the Sisters and she turned their weapons upon Peter Ratri and sided with the children. Although she acts as though she is only siding with the children because of their shared interests, truly Isabella retains her regrets and doesn't expect her children to forgive her since she doesn't forgive herself, is fine if they now hate her, and is genuinely touched that they still call her Mom. Even though she knows no good she does will undo the damage she has caused, Isabella vows to live on to atone what she did to her children and becomes extremely protective of them, and is even willing to lay down her life for them.
Taking care of the 38 orphans living in Grace Field House, feeding them, washing them, playing with them – Isabella went through the same routine every day in Grace Field, an orphanage where she acts as a substitute mother to all children.
On October 12th, 2045, Conny left the orphanage for adoption. Isabella accompanies Conny while she sings her favorite lullaby. However, in fact, Isabella shipped Conny off to become food for the demons, and gave the demons the word that she would soon ship off the highest-scoring children as well, unbeknown that Emma and Norman had witnessed and heared it all. The two return to the house running while being unnoticed but they leave Conny's little bunny behind. Isabella then finds little bunny at the scene, understanding that some children were there.
Isabella is thereafter seen in her secret room, contacting the headquarters, however, she doesn't mention anything about children having found out the secret. Isabella gives the task of preparing a room for Emma and Norman, but the real reason for it is so they can't mess up her plans and cannot escape. She also confronts and threatens Emma by checking her pulse. Ray, as Isabella's spy, confesses that Norman and Emma were the ones at the gate. Therefore, Isabella tries to discourage them by making it known that the children have tracking devices and that she can easily track them down. She also brings an adult helper, Sister Krone, to aid her and keep watch of the children.
Isabella keeps watching over the children from afar while she gets information from Ray. Isabella is seen caring for the children, including the newest addition to the family, Carol. She grows increasingly suspicious towards the children and their new tag strategies (which are actually training in disguise). She does not, however, interfere.
Several days later, Isabella presents Krone with official instructions that she is to be transferred out and become a Mama in another plantation. In reality, she had plans of getting her killed by the demons along with Grandmother. Meanwhile, she had also realized the orphans' plans about climbing the wall with the rope they had made. Isabella thereafter informs Ray that she had eliminated Krone and that she would also break her deal with him, and proceeds to lock him up in a room.
Isabella uses her tracking device to detect and find Norman and Emma, and she finds them by the wall and confronts them without her "Mama" facade, explaining that they should stop resisting, that they have lived happy and carefree lives and will die quickly. They refuse to accept this fate and Emma grabs Isabella so Norman can climb the wall, but Isabella breaks Emma's leg. Isabella then discloses that they are the best quality meat she has raised, fit for "the One", and that Norman will be shipped out the next day.
On Norman's shipment day, he says goodbye to everyone in the House. Isabella tries to interfere with Emma and Norman's conversation as she urged Norman to prepare to depart from the orphanage, but gives in to not seem suspicious to the children. Later, Isabella accompanied Norman to the gates of Grace Field and he questioned her whether is she happy. Isabella was in shock and hesitated for a moment, before replying that she was indeed happy. At the gate, Isabella ushers Norman into a side-room to wait for the demons.
After Norman's shipment, Isabella confronts a crying Emma in the infirmary, where she offers to sponsor her as a Mom candidate, saying if she completes her training she could return to the house as a Mother or Sister, but Emma refuses. Isabella is clearly upset and tries to discourage Emma by telling her that there was nothing except death that awaited them and that they would absolutely not be able to escape. In spite of this, Emma does not give in, and Isabella leaves with a pained expression.
For the following two months, Isabella kept a close eye on Emma and Ray so they would not plot anything new and plan for their escape. She also didn't suspect any other orphan doing something out of the ordinary.
On Ray's birthday and the night before his departure, Ray lights himself and the House on fire and as it spreads, the children evacuate. Isabella tries to extinguish the fire and save Ray, who she thinks is engulfed in flames, but the children had wrapped meat and hair in his clothes as a decoy. However, upon finding Emma's severed ear in a bucket, she realizes the children are alive and escaping, to which Isabella attempts to contact headquarters but finds the keyhole plugged. However, she manages to rescue the transmitter as the building burns.
While reuniting with Phil and the other small children left behind, Isabella notifies headquarters of the fire and that 15 children have escaped. When there is no sign of the children at the bridge, Isabella runs along the wall and arrives in time to see Emma, the last child, cross into the forest before the lines are cut. Isabella accepts defeat and wishes the children nothing but luck before removing the ropes in order to cover up their escape.
She then returns to the burning building where she tells Phil they successfully escaped and devotes herself to take care of the younger orphans as she sings Leslie's lullaby to them.
On January 15, 2046, following the escape of Emma, Ray, and the other 13 orphans, Isabella is reprimanded for her unforgivable mistakes by Grandmother. Isabella blames everything on herself and decides to take the responsibility on her own shoulders.
On January 17, 2046, it is revealed that Isabella was temporarily imprisoned for her mistakes. When Isabella expected to be killed off, Peter Ratri and the demons revealed that all of her mistakes and responsibilities as in letting the children escape were placed on Grandma Sarah. Although Isabella wasn't able to manage her products, Sarah wasn't able to manage Isabella. Additionally, Peter deemed Isabella's potential and abilities to be far more superior than Sarah's. As a result, Sarah was shipped out to be served at the upcoming Tifari in order to make up for the escapees.
Although Isabella initially was hesitant to take up the role as the new Grandmother after Sarah, Peter promised her real "salvation" and to take her out from the farm system if she succeeded in her job. Isabella eventually agreed after hearing Peter's proposal, wanting to destroy the number and chip in her chest, as well as save herself and other people around her with that knowledge.
On November 13, 2047, after the death of Queen Legravalima and the five regent heads, Isabella and Peter met up to discuss future plans. Isabella is mentioned to have managed Grace Field very well and has increased her breeding performance. Peter also reveals that he plans to resurrect Lambda 7214 into a new union of all Premium- and Factory Farms, and in the process abolishing every farm apart from Grace Field. One of Peter's subordinates states that it will be that day when Isabella could become a free woman. Peter soon requests Isabella to dispose of all the children who were to arrive soon, including the Grace Field escapees, to which she agrees.
Isabella soon decides to gather all the Mamas and Sisters of the Premium Farms. She quickly reveals that she is actually planning to betray the farm and assist the escapees when they arrive, and asks if there is anyone who is willing to stand up with her. The women are baffled by Isabella's confession, but she goes on to explain how she came to a realization shortly after she accepted the role of Grandma; that she, Sarah, and all the Sisters among the staff of Grace Field were still livestock to the Demons and the Ratri Clan and could still be shipped for even the slightest offense. Her recent thoughts and experiences, in realizing she'd sincerely loved her children, how Sarah was made to suffer the consequences of Isabella's own failure, and Isabella being given the promotion to Grandma, Isabella soon came to the conclusion that this life that she and all the Moms and Sisters were being made to live was a living hell and had no future despite the underlying motive of survival at all cost, something they'd all known deep down but just couldn't bring themselves to acknowledge it. She made her decision to betray Peter Ratri once her children returned to Grace Field and aid them in overthrowing the Ratri Clan and the Demons. Isabella lastly asks the women who agree with her to stand beside her, as she would show them "something very interesting".
As the Paradise Hideout inhabitants, including the Grace Field escapees, are kidnapped by Peter Ratri, they are transported to Grace Field House to once again be processed as food. Isabella meets Peter by the gate, being referred to as "Grandma Isabella". Isabella's children are utterly shocked to see her again.
After the kids were interrogated by Peter, Isabella arrives once again and hugs her children close while they beg her to perform first aid on Nat's finger as it had been broken by Peter. She goes over to Nat and breaks the rest of his fingers. Isabella then tells the children that she will start disposing of them in order. Just as the children think that all is lost, Emma, Ray, and Norman arrive at the scene, fully armed and ready to save the children.
When Peter was finally held captive by the children, he calls upon Isabella to save him. She then appears with all the other Mamas and Sisters, armed. She aims at Emma, having a short talk with her. She then aims at Peter; telling the children that they did well, in the process betraying Peter. Isabella tells Peter that her betrayal is obvious since both the children and adults are his enemy. Isabella explains to Emma and the rest that her reason for assisting them is that they happen to share the interests, that she was getting fed up with her life, and that she didn't like the future Peter described for her. Isabella thinks to herself how she doesn't expect Emma and her other children's forgiveness and is fine with them hating her, but Emma stands beside Isabella and calls her "Mom", pointing her gun at Peter. However, in the last minute, Peter is able to flee.
When Isabella meets the others at the Grace Field Farm, a demon comes and about to kill Emma. It turns out that Isabella tackled the demon's attack, thus injuring her. After the demon released his claw, Isabella fell to the ground in critical condition. It turns out that the escapees and the other children already forgave Isabella for everything. Isabella ended her life after apologizing to Ray for everything she had done to him.  
Skills and Abilities
Isabella has shown that she is very intelligent and can notice the smallest of details. She quickly and easily discovered the children's plan to escape and has been able to keep all her children healthy and top of the line. She is also very adept at chess and has not once lost to her children, further proving her sharp intellect.
From being able to lift Emma off the ground and breaking her leg with ease and lifting heavy objects, Isabella has proven herself to be physically strong.
I must live for myself, and to give purpose to Leslie's life.
— Isabella stating that her relationship with Leslie gave her the reason to live.
Leslie is a childhood sweetheart of Isabella's, and the closest friend she had during her innocent years in the orphanage they were raised in. Isabella was often shown to be free-spirited and chummy when she was with Leslie. When Leslie hummed a tune he composed, Isabella eavesdropped him and later encouraged him to share it with her. The boy was shy with her request at humming his tune to her at first but later decided to after blushing from seeing Isabella's enthusiastic smile. The two soon chanted the tune together. In the anime, Leslie did not chant the tune of his to Isabella, he used an instrument to play the tune out for her.
Tragedy struck as Leslie was sent off to get killed by the demons – a painful revelation Isabella eventually knew after discovering the dark secrets and evil doings of her orphanage and her caretaker. After Isabella failed to escape the orphanage when she discovered a steep cliff that surrounds the outside of the walls, she was soon sent off by orders from Grandmother. Knowing how Leslie has passed gravely affected her, as she described his death to have unbelievably frustrated her, Isabella is now a shadow of her free-spirited and lively self. This evidently showed how strong her love for Leslie is, to the degree of losing the personality that once defined her.
On the flip side of the coin, though Leslie has passed, Isabella's memories of him and the tune they had between them invigorated her and gave her strength and the meaning to live on. Isabella's love for Leslie was also the reason why she chose to become a caretaker instead of getting killed. Leslie's tune, which Isabella still reminisced to this day, was sung during the time when she was pregnant as she shared the tune to her unborn baby to provide herself solace.
When she first met him, Isabella believed Ray to be just another orphan. She raised him like every other child at Grace Field, with love, care, and affection before they would be shipped off and ultimately killed. But at some point, she overheard Ray whistling the same tune she had whistled during her pregnancy, the same tune that her childhood sweetheart Leslie had taught her. She then understood that Ray was her own son who she now was forced to raise as livestock — a revelation which left Isabella in utter horror. Ray, also having figured out their familial connection, asked her why she gave birth to him. While Isabella was momentarily shocked, she coldly responded so that she could live.
Since Ray had found out the truth about the orphanage and everything else, Isabella agreed to make him her spy to monitor all the children in her care in exchange for him getting different gifts from the outside world. Despite their biological connection, their relationship was purely "professional", and unlike with the other children, Isabella was always her cold, level-headed and rational self around Ray. Despite having him around and having him aid her for six years, Isabella had little trust in Ray and only saw him as her own "underdog". When she dismisses Ray as her spy, she does tell him she would've liked to keep him by her side to the end and apologizes to him.
It is also implied that both sides felt little love towards each other. Isabella showed no remorse or concern when she revealed that he would get shipped off and killed soon. Additionally, when she thought that Ray was engulfed in the flames during the escape, she only cared about saving Ray's brain for the demons.
However, at the end, when several of her children succeeded in escaping Grace Field after she herself had deemed the prospect impossible, Isabella secretly hoped and prayed for them to survive, to live, to have the courage she never did. She also realizes how much she actually loved her son Ray.
Isabella served as Emma's Mama in Grace Field House and raised her with love and affection as her own daughter. Isabella stated that she loved Emma for being so considerate towards her family. Emma, in return, loved Isabella just as much and the fact that they weren't blood-related didn't matter to her. For Emma, Isabella was her one and only mother that taught and raised her. However, this soon changes when Emma finds out the truth about Isabella and the orphanage. Emma becomes devastated and grows fearful and spiteful towards Isabella, seeing her nothing but as a threat for her family. When Isabella realized that she had found out about the secrets of the House, she was not afraid to confront Emma and threaten her verbally, emotionally and physically. Everything Isabella did, threating to kill Emma, breaking her knee and discouraging her to escape, was for the sake of "protecting" her since she loved her and didn't want her to suffer. At the same time, Isabella also had great faith in Emma's abilities and had therefore been raising her as the Mama candidate of the farm. She later gives this offer to Emma personally herself, but the latter refuses.
Although Isabella did everything in her power to discourage and prevent Emma from escaping, she gracefully admits her loss when Emma and the other children manage to escape. Isabella then wishes for her to be safe and survive, and she also reflects on how she wishes she could have loved her normally.
Like every other orphan, Isabella raised Norman as her beloved son. Norman, in return, adored his foster mother very much. However, after Norman found out the truth about her and the orphanage, Norman's love towards Isabella shattered and he began seeing her nothing more than a threat. Though Isabella claims that she loves him and doesn't want him to suffer, she had a smug face when she revealed, without any hesitation, that she would ship Norman off. Despite the circumstances and their tense relationship, both parties were able to "get along" in front of the other children and converse normally. Isabella also acknowledges Norman's selflessness for choosing to be shipped off instead of escaping, displaying respect and praising him for it. Additionally, when Isabella was asked if she was happy, she responded that she was indeed happy, because she had met someone like him. Isabella later reflects on how she wishes she could have loved Norman and all the other children normally.
When Norman was transferred to the experimentation plantation Λ7214, Isabella hugged Norman close, told him that she loved him, but also that he would never be able to leave the new plantation he would be residing on. She also wishes him nothing but the best, despite knowing about his eventual fate.
Isabella served as the Mama of all of the Grace Field Orphans. Despite knowing of their tragic fates, Isabella genuinely loved them and was determined to shower them with love before their deaths. She was able to win the trust and love of all children since she was the only parent-figure they had in their lives. When the older children found out the truth about the House and everything else, Isabella still adored them but was extremely violent and manipulative towards them since she didn't want to "suffer". However, when they escape, Isabella wishes her children nothing but the best and secretly hopes for them all to survive. She also mentions that she wishes she could have loved them normally like a normal mother. As for the other children who were left behind and oblivious about the dark secrets, Isabella devoted herself to care for them for as long as she could despite knowing of the consequences she would have to face for letting 15 of the children escape.
When the escapees (minus Emma, Norman, and Ray) were returned to Grace Field, they were shocked to see that not only was Isabella alive but she had been promoted to the position of Grandma. Although she approached them with a maternal welcome, giving a couple of them a hug, she shortly after took Nat's hand (after some of his fingers had been broken by Peter Ratri) and proceeded to break the rest of them, and informed her wayward children that they were to be disposed of, all the while smiling at them with a depraved look. This shows that although she displays the motherly love she has always done, she prioritizes her own life and safety over that of her children.
Krone was sent to Isabella as Sister to aid Isabella in supervising the Grace Field orphans. Krone and Isabella's relationship was work-based, and Krone soon showed signs of defiance toward Isabella and hatred for her. As Krone worked to throw Isabella off of the Mama position, Isabella was a step ahead of Krone. Both women were cold, manipulative and distrustful towards one another, though they showed a healthy friendship in front of the kids. Isabella despised Krone's sweet talk to her and instead opted for her to work hard, though when Isabella felt that Krone had become useless to her, she had her to be eliminated by the demons. In the end, Isabella wonders if the children could have escaped if she had kept Krone around, implying that Isabella does acknowledge her skills.
Sarah was Isabella's Mama in Grace Field before being promoted to Grandmother. During her childhood, Sarah prevented from escaping and later recommended Isabella to become the next Mama of Grace Field. For the following years, Isabella followed in her footsteps and in the present day, seem to have a rather normal and respectful alliance. Sarah describes Isabella as one of her important pawns and will not let her title as a Mama be taken away. However, Sarah is seen being extremely disappointed in Isabella for letting the children escape, as she couldn't believe that Isabella, considering her abilities, allowed that to happen.
After the escape of the 15 orphans from plantation 3, although it was expected that Isabella had to face the consequences of the escape, it was actually Sarah who was given the punishment. Isabella appeared to be devastated by her demise.
- According to Kaiu Shirai, he made the main protagonist a female because Isabella is the first antagonist to be a female too, hence thinking that the mother-daughter relationship between the two would make the story "more interesting".
- In an interview, Posuka Demizu mentioned that she enjoys drawing Isabella, and thinks that she is a character that should be drawn beautifully.
- Kaiu Shirai discussed about Isabella's character design in an interview which was published in Volume 13 Special Edition. The following is what the author said.
- "I requested "a woman who is poised and dignified, like a soldier and like a ballerina" and "make her a mom, not a teacher or a maid." Demizu-sensei adds idiosyncratic features to the designs depending on their characteristics, so that you can distinguish them by their silhouettes, but it turned out that if she did that for Isabella, it would look wrong. So it ended up that "Isabella's lack of distinguishing characteristics is her distinguishing characteristic." Because of that, she has basically the same kind of design as in my makeshift drawings from the original breakdowns. That turned out to look dignified and refined because it's Demizu-sensei's version of Isabella. Since her design didn't change much, it's easy for me to draw when I'm signing autographs."
- Isabella is not only the youngest to ever reach the position of Mama, being appointed in her early-twenties, but her farm has the best track record of shipping quality children.
- Her name means "devoted to God" in Hebrew, which may relate to her being a servant to the demons.
- The following are Isabella's rankings in some of The Promised Neverland's official popularity polls.
- Isabella is the Spanish and Italian variation of Elizabeth, which is derived from the Hebrew name Elisheba.
- Its meaning translates to "pledged" or "devoted to God."
- Isabella and Elizabeth have been interchanged in England since the 13th century.
